TRUCK.

To all whom z'z may concern.'

Be it Iknown 'that we, OLor OLSON and ANDREW OLSON, citizens of thelUnited States, residing at Kingsburg, in the county of Fresno, State ofCalifornia, have invented a new and useful Truck; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will'enable others skilled in theart to which` itappertains to make and use the same. Y

This invention relates to trucks and is yparticularly a truck for use invineyards and places where short turns are required.

An object of the invention is to provide a device of this kind havingbars that will perform double functions'such as acting asl reach barsand steering means for the rear axle. These reach bars are madeflexible, so that they may give and bend Without breaking and willreturn to their original shape when the strain which' causes them tobend is removed. The invention is further di rected to the reduction ofthe number of accidents resulting from the breaking of the reach whenstraightening a truck after a sharp turn is made with most ofthe load onone side, as the flexibility of the reach bars adapts them to adjustthemselves quickly to all variations of strain, such as irregularitiesof the ground. The manner of construction precludes the binding orfriction of the cross reachers and the truck as a whole is designedparticularly to meet the needs peculiar to orchards.

In the drawings Figure 1 is a side elevation of the invention.

Fig. 2 is a longitudinal section taken vertically through the center ofthe truck.

Fig. 3 is a bottom plan view.

Fig. 4 is a' transverse sectional View `on line 4 4 of Fig. 1 throughthe rear axle and turn table.

Fig. 5 is a transverse section through the forward axle and turn tableon line 5-5 of Fig. 1.

Fig. 6 is a table.

Fig. 7 is a plan of the rear axle and turn table.

Fig. 8 is a sectional view on line 8-8 of Fig. 6 showing the method ofconnecting one cross reach tothe front axle.

Fig. 9 is a sectional view on line 4 4 of plan of the front axle andturn SerialNo. 139,660.

Fig. 6, showing the structure forr Connecting the other cross reach tothe axle.

In the drawings,-the truck platform is the timbers 1 bers at either end.The longitudinal reach 4 extends from the forward turn table to the rearturn table and between it and the truck platform the longitudinal timber5 intervenes. The cross pieces 6 act as bolsters for the `platform overboth the lforward and rear axles. The short pieces 7 resting on the endsof the reach 4'a`but the cross ypieces 6 and adjoin the centrallongitudinal timber 1 of the platform. l l v On the axles 9 the wheels10 are secured in any conventional manner `and at the center of the axlethe bottom half 11 of the turn table is secured by the bolts 12.' Theupper half 13 of the turn table is lsecured to the reach 4 and the truckplatform by four bolts, a bolt 14 passing through the reach 4 the shortpiece v7' and the central longitudinal timber 1 and beimg'secured on topof the platform by a nut 15. The platform at this point is countersunkto the nut. The bolt 16 is diametrically opposite the bolt 14 andsecures the upper half 13 of the turn table only to the reach 4, aslot-in 4 making room for the nut 17. .The bolts 18 serve to fasten 13to the cross piece 6 and in so doing pass through the pieces 18a whichserve to partly transmit the weight of the body to the axle.r

The nuts 19 act as a securing means for the bolts 18 on the upper edgeof the cross piece 6. The king-bolt 20 connects the two halves 11 and 13of the turn table together, the reach 4 being recessed to make room forthe head of thel bolt'and its attendant washer.

On either side of the turn table isY a clamping device composed of thestirrup 21 which kThese clamping devices on either side of the same axleare oppositely applied. They are so disposed on the two axles that theclamp` Speccaton of Letters Patent. Patented @$13. 23, 1917i iApplication led December 29, 1916.
